Tinline Bay is a cove and beach located within The Abel Tasman National Park in the South Island of New Zealand.
It is located approximately 2 kilometres from the entrance to the park near Mārahau and is the southern start of The Abel Tasman Inland Track.[1] A sandy beach, it is a popular stopping off point for hikers, and for kayakers from the Tasman Sea. It is also the site of a Department of Conservation campsite.[2]
Tinline Stream flows into the bay. John Tinline lived for some time in nearby Mārahau and both the waterway and the bay are named after him.[3]
